Happened to one out of four of my dhr2 dh casing too. After a few rides It now holds air but will still deflate faster overtime than the assegai dh casing it's paired with.

interesting design choice. Putting the trunnion bearing on the shock eye that doesn't rotate much. Water bottle clearance for smaller sizes?

I thought about that. Should save a bit of weight as well hah.

Yeah, need to make sure it clears the crank arm and frame. Will be 3d printing one for testing as soon as the sprockets I ordered arrive. It should be an easy fix though, just make the lock ring thinner etc. it's for my own bike design so I'm able to

The idler on my bike needs replacing and they are pricey for what they are. I tried finding a cheaper solution and came across fixie sprockets. It seems possible to design a carrier for it. This is my interpretation that requires a bb tool ... more »

I think melonhead is saying the longest stroke you can get for a 230mm shock is 65mm. a trunion 225x75 shock is shorter than 230mm so it's possible to use that for DH application, might not even need to change the rocker.

I actually checked before that PB bike check went live. Looks like the stock linkage and shock. 162mm in my rough drawing

The Kavenz bike is another production high pivot horst link. If you follow their social media you would have came across the incident when they had to redesign their idler location moving it from the chainstay to make it concentric to the main pivot, ... more »

the center of the idler is concentric with the main pivot so the chainline goes above it resulting in less anti-squat.

I did a rough plot of the Range in Linkage and it shows the anti-squat to be very low. I designed a bike with a similar layout and had to put the idler lower than the main pivot and on the seatstay to get 100%+ anti-squat.

Someone then dm'ed me saying he holds the patent to the design and will be asking for a licensing fee if I intend to sell my bike. Pretty sure that's the reason Norco didn't put the idler lower.

Would like to see some graphs. Anti-squat might be below 100% since the idler is concentric to the fixed pivot. Maybe their hands were tied because someone was asking for a licensing fee that they were not willing to pay.

It's quite plush but feels like lacking midstroke support. Also feels like hitting an abrupt wall deep in the travel without nearing the bottom out. Returned to about 28% and feels just right. Cool looking bike by the way. Is the 3d printed one actually

Don't notice a clicking noise, but it does make a sloshing sound. Rebound is way too slow on mine, I need a retune.

All bike brands should also publish actual seat angle and offset so we can easily calculate our top tube length at our preferred saddle height, but I'm guessing 60 something seat angle doesn't look good on paper.

Based on the leaked catalog picture, there seems to be enough room to run a shock with a longer stroke, say maybe 75mm. Based on my own bike design, the rearward axle path will make enough clearance for 200mm or more travel. The only problem will be ... more »

Digging all the downduro builds. I'm loving my MK2. Overbiked 99% of the time but rides like a dream.
